the information of all kinds of event generated in the operation process of Radius protocol,

30.9 radius nas-ipv4
Command: radius nas-ipv4 <ip-address>
no radius nas-ipv4
Function: Configure the source IP address for RADIUS packet sent by the switch. The
―no radius nas-ipv4‖ command deletes the configuration.
Parameter: <ip-address> is the source IP address of the RADIUS packet, in dotted
decimal notation, it must be a valid unicast IP address.
Default: No specific source IP address for RADIUS packet is configured, the IP address
of the interface from which the RADIUS packets are sent is used as source IP address of
RADIUS packet.
Command mode: Global Mode.
Usage guide: The source IP address must belongs to one of the IP interface of the switch,
otherwise an failure message of binding IP address will be returned when the switch send
RADIUS packet. We suggest using the IP address of loopback interface as source IP
address, it avoids that the packets from RADIUS server are dropped when the interface
link-down.
Example: Configure the source ip address of RADIUS packet as 192.168.2.254.
